 =====
 Use RHEL 7 cloud images as the baseline for built disk images.
 
-Note: As of this writing, RHEL 7 is still in beta, so final download
-locations are not available.  This element defaults to using the RHEL 6.5
-image, but that will need to be overridden using the appropriate DIB_*
-environment variables to point at a RHEL 7 image.
+Because RHEL 7 base images are not publicly available, it is necessary to first
+download the RHEL 7 cloud image from the Red Hat Customer Portal and pass the
+path to the resulting file to disk-image-create as the ``DIB_LOCAL_IMAGE``
+environment variable.
 
-For further details see the redhat-common README.
+The cloud image can be found at (login required):
+https://access.redhat.com/downloads/content/69/ver=/rhel---7/7.1/x86_64/product-downloads
+
+Then before running the image build, define DIB_LOCAL_IMAGE (replace the file
+name with the one downloaded, if it differs from the example)::
+  export DIB_LOCAL_IMAGE=rhel-guest-image-7.1-20150224.0.x86_64.qcow2
+
+The downloaded file will then be used as the basis for any subsequent image
+builds.
+
+For further details about building RHEL 7 images, see the rhel-common and
+redhat-common element README files.
